COMBINED INTERNAL-connusfrion ENGINEAND MAGNETO.

To all whom 'Zi' 'may concern:

Be it known that I, RICHARD citizen of the United States, residing at South Bend, in the county f St. Joseph and State of indiana, have invented certain new and useful Improvementsin Combined internal-Combustion Engines and Magnetos, of which the following is aspeciflcation.

My invention relates to a combined inter-Jn nal combustion engine` and magneto and it appertains moreY especially tothe distinctive features pointed out in the annexed claims.

The purpose of my invention is to provide a structurally combined magneto and crank case head of;l internalA combustion engines; to provide a crank case head that shall at the same time support -a magneto armature l and provide a bearingfor the crank shaft I that shall support a armature whether combined with the crank shaft bearing ornot; that shall secure to the projecting shaft. a` rotatable casing adapted to support afield magnet the whole constituting a major or secondary fly wheel for the `engine; vand that shall be capable of utilizing any special foris or types of magnetos in which alstator is supported. by an armature plate which' at the same time serves as a part of, or is attached directly case, in concentric relation to the crank shaft.

With these and 1. stances of adapt-ation as will disclose the bearing.

prises A Fig. 4 is an elevation in section of a -supplemental armature' plate and provision therefrom for spark advance and retard.

In its broadest sense this invention co1ndynamo electric machine. The stationary element of such machine being supported by, or forming apart of, the crank case head and the moving member thereof being carried adjacent thereto by the main shaft of the prime mover.

An adaptation of the invention may corn- A. OGLSBY,

Patented Aug., 13 319118, Application filed January 5, i917. Serial No. 140,795. i

the features instanced initlie accomprise drawing wherein asworking" cylin-y panying Ader l is supported on a crank case head 3' having a base 2 thereumder. The crank shaft 4 is carried in the head 3 at oneend and 'another head at the other end. This shaft mayhave one or moreicollars 5 to take the end thrust of the shaft. A-suitablebearmg sleeve 8 or bushings 9 may -be placed in the vcombined armature plate and which is held on head 3 by bolts lll.

head 10 The shaft t has a tapered end Son which y the magnet supporting flanged 'hub 23 is secured bya nut L lThe flanged hub 23 sup ports the flanged magnet casing 20. These parts may constitute a major or secondary fly wheel or the casing 20 may only serve as. to\which it is suitably secured. Laminated poleends 22.

a carrierv for the magnet 21 arelalso secured to fthe casing adjacent the ends of the magnet on each side of its air gap. As'theshaft 4 revolves the magnet 2l is carried past the armature heads '13.

These are attached to the armature plate l0.v A core 25 joins them.` 0n the core the armature coil l2 which may consist of a primary 'andsecondaryrwfinding is placed'. A.,

ground connection is formed at la.

1The primary circuit is broken 4at ,17 by a cam 26 attached tothe magnet casing 20 whenever. the cam engages shoevl of 'the circuit breaker arm 16.' A condenser 18.'

may be connected lacross the break17 and an'external circuit7 terminal is formed at 19, the other side being completed through the ground. It is immaterial for what pur:

pose the generated current isused or in what ,y

way it is distributed.

The flanged supporting hub 23 is secured screws or vrivets 24 or 1n any other manner desired. yIt is of course obvious that, if found expedient, the cas- Y 4 ing 2O and'ypart 23 may be formed 1n one i piece, though the posslbility of standard.

izing the flanged hub 23 and adapting it tov various sizes and shapes of fly Wheels or casings 20 would not then be present. I may makethese parts in any suitable wav that lthe exigencias of variable practical demands may require. 4

It should be understoodthat this invention is not limited to the specific details Aof an .instanced adaptation shown and describedbut broadly covers any form of combined lmagneto and crank casing heads. v

Whenever it isfdesired to shift the armaable end plate to shaft having stat-lona ry ture position With respect to the recurrent position of the circuitbreaking cam 26 I may provide a supplemental armature plate 30 having shouldered bearing in plate l0 and held thereon by means of shoulder screws 31 passing through curved slots inthe plate 30. The screws also serve to hold plate l0 onto head 3 While at the same time permitting of rotative movement of the plate 30 on such screws. An arm 33 projects from plate 30 through a slotted hole 32 formed in plate l0 and a spark control link 34 is secured to its outer end. This provision is of course not needed if a fixed spark relation is to be served by, the magneto. l

lVhat I claim is,

,1, In internal combustion engines, a crank case, a shouldered end plate, a bearing therein central of the shoulder, a Crank shaft in the bearing and projecting loutside of the same, an armature the outer face of the plate, and a field mag-4 net-carried by the shaft external of the plate.

An internal combustion engine, comprising a cylinder and a crank case, a'removbearing in the said case and the end plate, means for retaining the plate in the case central of the shaft axis, a stationary armature supported to one side of the shaft on such plate, and a field magnet carried by the outer end of the crank shaft.

3. A. prime mover, comprising a crank case, a bearingat one end thereof, a crank shaft therein, the casehaving an enlarged opening at the other end concentric with the shaft, a removable plate adapted to cover the opening, a bearing therein for the shaft, means for supporting the plate so as to maintain the bearing and opening inconcentric relation, an armature coil supported by the plate to ture heads 4for said coil the' other face of which is concentric with the sha-ft, and a field magnet carrled by the shaft external of the plate the poles of Awhich are also concentricwith the shaft and adapted to function adjacentlthe armature heads. In internal combustion engines a crank an annular shoulder on such to be supported b armature secured to a field magnet coperating therewith carried by the outer end of the shaft. y

5. n internal combustion engines, a crank case, and a. removable end plate therefor 'tached to coil supported adjacent j the crank case, a crank` f thevenlarged opening, a3 thel plate, and

shaft external of the armature, and a field magnet attached to the fly Wheel.

In internal combustion engines, a crank case, a shaft rotatable therein, a removable end plate for said case also serving as a bearing for shaft, anV armature supported by the plate, a circuit breaker and condenser placed adjacent thereto, a field magnet atthe shaft adapted to pass by the armature, and acam carried by the shaft for periodically operating the circuit breaker as the shaft is revolved.

8. In internal'combustion engines, a crank case, a removable end plate therefor, a crank shaft rotatable therein, a fiy Wheel a field magnet and. cam carried 4by the shaft, anarmature comprising a coil connected to a-circrank ycase end plate adjacent the path of travel of the field magnet, and adapted through such rotation to have periodic currents generated in its coil and the circuit breaker actuated by the cam as the shaft revolves.
